PNEUMATIC FLOAT VALVE DESCRIPTION The Magnetic is an air sensor for detecting liquid level inside a vessel. The float mechanism mounted within the vessel operates a ceramic coated magnet.

Both side mounted and top mounted valves are available either as normally closed or normally open.

1 PNEUMATIC FLOAT VALVE DESCRIPTION The Magnetic is an air sensor for detecting liquid level inside a vessel. The float mechanism mounted within the vessel operates a ceramic coated magnet. As the float moves it pivots the magnet. A magnetically actuated sensor on the outside of the solid metal housing reacts to the inner magnet movement. The movement shifts a 3-way air valve. Both side mounted and top mounted valves are available either as normally closed or normally open. FEATURES Explosion Proof No electrical hazard For vented or non-vented vessels Stainless steel float mechanism Side mounting or top mounting selection 3-way pneumatic valve Actuation indicator on 3 way valve Magnetic coupling-float to valve Minimum air usage SYMBOLS Normally Closed Normally closed float valves are "off" (no output) when float is low. Air signal is "on" when float is raised. Normally Open Normally open float valves are "on" when float is low. Air signal is "off" when float is raised.

3 LEVEL INDICATOR AND CONTROL APPLICATIONS Normally Closed Indicator Indicator Signal "On" (Port ) when level is high. Normally Open Normally closed float valve (side or top mounted). Output signal (port ) of level sensor is "on" when level is high. Output can actuate an indicator, pressure switch, air pilot power valve, etc. Can be used with High Level Indicator panel shown on page 4. Normally open float valve (side or top mounted). Output signal (port ) of level sensor is "on" when level is low. Output can actuate an indicator, pressure switch, air pilot power valve, etc. Can be used with Low Level Indicator panel shown on page 4. LEVEL CONTROL WIDEBAND LEVEL CONTROL NARROWBAND Valve Valve Normally Closed Normally Open Detented Air Valve Normally Open Two level sensors required; one normally closed for high level, one normally open for low level. The control automatically maintains the level between the location of the two sensors. Minimum "high/low" is approximately two inches. Maximum "high/low" is set by the location of the two sensors. Can be used with Wideband Level Control panel on page 4. One normally open float valve provides the control for narrowband level control. Level is maintained within approximately /". Output can actuate an air operated power valve for direct fill, or for control of an air operated pump through an air operated power valve. The output can be used with the Narrowband Level Control panel shown on page 4. O'Keefe Controls Co. 007 All Rights Reserved

4 To High To Low This panel is used for indication of level only. When a normally closed float valve is actuated by high liquid level the indicator shows "red". The indicator shows green when the float valve is not actuated. Part No. OKC-89F Includes inlet filter, regulator Part No. OKC-89 Filter, regulator and gage not Use the high level indicator panel with a normally closed float valve. OKC-536- OKC-570- OKC-536- OKC-570- This panel is used for indication of level only. When a normally open float valve is deactuated by low liquid level the indicator shows "red". The indicator shows green when the float valve is actuated by the liquid level.

OKC-50- OKC-7- OKC-50- OKC-7- Form OK-4R WIDEBAND LEVEL CONTROL To Control Valve or Pump NARROWBAND LEVEL CONTROL To Control Valve or Pump To High To Low To Level Sensor WIDEBAND LEVEL CONTROL This panel is used for control of liquid between two levels. The control panel pilots a fill or drain valve, or controls a power valve that operates a pump. A normally closed float valve is used to sense the high level. A normally open float valve is used to sense the low level. Part No. OKC-9F Includes inlet filter, regulator Part No. OKC-37F (same as OKC-9F but configured for Pump Down operations.) OKC-9F panel indicator shows green after the high level is reached and continues to indicate green until the low level is reached. After the low level sensor is deactuated the indicator shows "red" until the high level sensor is actuated. (OKC-37F shows "red" during pump down.) When the panel indicator shows "green" the output signal is "off". When the panel indicator shows "red" the output signal is "on." NARROWBAND LEVEL CONTROL This panel is used for control of liquid level over the deadband of the pneumatic float valve (approximately /4" to /"). The control panel pilots a fill or drain valve that operates a pump. A normally open float valve is used. The output control is "on" (indicator red) when the level is low and is "off" when the level is high (indicator green). Part No. OKC-9F Includes inlet filter, regulator Part No. OKC-9 Filter, regulator and gage not The output signal can also be used as a remote indicator signal to operate a visual indicator or a sonic alarm. Use as follows: Low Level Alarm use a normally open float valve High Level Alarm use a normally closed float valve O'Keefe Controls Co. 007 All Rights Reserved Operation A pneumatic control panel Box Dimensions 4" x 4" x -5/8" Inlet Air Pressure to Regulator 50-5 psig Normal Pressure Setting psig Pneumatic Indicator " diameter red/green Manual Control OFF/ON Toggle Valve Air Filtration Air should be dry and filtered to 5 microns Output Air Signal psig (same as regulator pressure setting)
